Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572646, here are decompositions:

7 + 572639 = 572646
13 + 572633 = 572646
17 + 572629 = 572646
37 + 572609 = 572646
47 + 572599 = 572646
59 + 572587 = 572646
73 + 572573 = 572646
79 + 572567 = 572646

Showing the first eight; more decompositions exist.
